Bug#540549: grub-pc: General problem with dmraid devices

[root]

Package: grub-pc
Version: 1.96+20090808-1
Severity: normal

Hi,

googling this topic I found some threads concerning this problem in the upstreams devel mailing list:
http://lists.gnu.org/archive/html/grub-devel/2009-06/msg00264.html
http://lists.gnu.org/archive/html/grub-devel/2009-07/msg00509.html

So the maintainers know about the problem and since there were some patches I tested the unstable
version from August 08. But still the same 'no mapping exists' error. Here is the output, please
excuse the german parts:

done

So I thought perhaps it is the device.map and added some fancy entries for my dmraid devices:
# cat device.map
(hd0)	/dev/mapper/isw_gcbehhdgb_Volume0
(hd0,0)	/dev/mapper/isw_gcbehhdgb_Volume01
(hd0,1)	/dev/mapper/isw_gcbehhdgb_Volume02
(hd0,5)	/dev/mapper/isw_gcbehhdgb_Volume06
(hd0,4)	/dev/mapper/isw_gcbehhdgb_Volume05
(hd2)	/dev/sda

Unluckily, still the same errors:
# grub-install --modules="linux pc raid ext2 jfs biosdisk" /dev/mapper/isw_gcbehhdgb_Volume01 
grub-probe: error: no mapping exists for `isw_gcbehhdgb_Volume01'
grub-probe: error: no mapping exists for `isw_gcbehhdgb_Volume01'
grub-setup: error: no mapping exists for `isw_gcbehhdgb_Volume01'

No solution in sight on my side.

Thanks,
Cornell
